DOOR AND LIKE FASTENER.

Specification of Letters Patent.

Patented June 22, 1909.

' Application filed June 3, 1908. Serial No. 436,361.

To all whom it may concern:

Be it known that I, FREDERICK G. PARKER, Sr. citizen of the UnitedStates, residing at Alameda, in the county of Alameda and State ofCalifornia, have invented new and useful Improvements in Door and LikeFasteners, of which the following is a specification.

My invention relates to a means for securing doors, in addition to theusual locks and fastenings for such purpose.

It consists in the novel combination of parts, and in details ofconstruction which will be more fully explained by reference to theaccompanying drawings, in which- Figure 1 is a transverse sectionalelevation of a door provided with my invention. Fig. 2 is a front viewthereof: and Fig. 3 is a horizontal sectional view.

It is the object of my invention to provide a means additional to theusual locks of doors, windows and like openings, by which a supplementalsecuring device may be conveniently connected and maintained in positionfor ready use.

As shown in the drawings, A is the escutcheon having a key-hole made inthe lower part for the key 2, and an opening through the upper part forthe knob shank.

The outside knob may be of the usual, or any convenient form. The insideknob 3 is made of suitable ornamental form as shown, and has a hole madethrough it lengthwise for the reception of a bolt 4, when the latter isnot in use. The upper part of the knob 3 has a depression or soc :et toreceive the head of the bolt, so that the latter forms an ornamentalfixture while in place. The shank of the knob 3 has formed u on it aring 5 having a hole made transverse y through it. This hole is in linewith the door casing, and upon or let into the casing is a plate 6having a screw-threaded hole made in it in direct line with the ring 5.

The bolt 4 is made of such diameter as to easily slip through theopening in the ring 5, and its end is screw-threaded so as to fit thethreads in the socket-piece 6.

The length of the bolt is such that when screwed into" the socket-piece,the bolt-head will approximately abut against the ring, and

thus hold the knob rigidly so it cannot be turned. The latch which isactuated by the knob thus becomes a permanent look while the bolt 5 isin this position.

The bolt awill, when disengaged from the ring in its locking position,be placed in the vertical opening in the knob, and the supplementallocking device will thus be kept convenient for use whenever desired,and with no danger of loss from displacement.

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. The combination with a latch turning knob, of ahorizontally perforated ring, a bolt slidable there-through, asocket-piece fixed to the door casing, and means for looking the end ofthe bolt in said socket.

2. The combination of a knob having a vertical opening made therethroughsaid knob having a portion provided with a transverse opening, a boltadapted to extend through the transverse opening and to engage a socketpiece upon the door casing, and means for supporting the bolt within thever tical opening of the knob, when said bolt is disengaged from saidsocket piece.

3. In a door latch and like, the combination of a knob having a verticalopening therethrough, said knob having a ring portion formed with it and)rovided with a horizontal opening, a bolt fitting each of saidopenings, and a socket upon the door casing with which the end of thebolt engages when the bolt is seated in said horizontal opening.

4. The combination in a door lock or latch, of a knob having a verticalopening made there-through, a removable bolt adapted to be normallycarried in said opening, an extension of the knob having a horizontalopening made there-through adapted to receive the bolt when removed fromthe knob, and a socket-piece with which the end of the bolt is engaged.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
